I need to find the $V$ by triple integral.
the limits from up is (1) - ecliptic cone.
and from dwon - (2) - elepsoide.
$$(1) \ \ \ \ z=-\sqrt{3x^2+5y^2}$$ $$(2) \ \ \ \ {3 \over 10}x^2+5y^2+{z^2 \over 3}=8$$
I try to use:
$x=5r\cos\theta$
$y=3r\sin\theta$
$z=z$
but I'm not sure it's good coordinate and I can't find the limit.
